Erection of rear extension and first floor extension and installation of replacement roof tiles to front and integrated photovoltaic roof tiles to...

General Policy 2

Requires development in residential zoning to respect site/surroundings in siting/layout/scale/design (b), not adversely affect landscape/townscape character (c), and not harm local residents' amenity/locality character (g). Officer found proposal complies as extensions are subordinate, match materials/design, screened from view, fit streetscene precedents, and cause no material amenity harm.

Environment Policy 4

Judges alternative energy developments (including solar panels) against environmental policies; larger installations like wind may need EIA. Officer confirmed PV tiles have no adverse impacts, support Strategic Plan renewable energy objectives (para 12.2.8), contribute to property energy efficiency, and no EIA required.

Residential Design Guidance 3.2 Potential Visual Impact of an Extension upon the Existing House

Extensions should match roof pitch/shape, ridge lower than main building; pitched roofs preferred over flat, especially if publicly viewable. First-floor extension complies (lower ridge, matching pitch); rear flat-roof sunroom at variance but accepted as proportionate, matching materials, subordinate, and well-hidden from public view.

Type A: Uplands

Single-storey rear extensions assessed for loss of light/overbearing impact, especially near boundaries in semi-detached properties; depth key factor, tunnelling effect to avoid. 4m projection acceptable as west of neighbour (reduces light loss), no overbearing/tunnelling, and neighbours unconcerned.

IoM Residential Design Guide - 7.3 Loss of Light/Overshadowing

No significant daylight/overshadowing loss to habitable rooms/gardens; assess sun path. Minor light impact to neighbour kitchen door but position/seasonal factors limit effect; rarely used area already shaded by boundaries/shrubbery.
